True Exposure is an HC/HCD lens function that allows the
shutter speed to remain un-aected when stopping down.
This eect is perhaps not so commonly understood as it is
restricted specically to integral lens shutters as opposed to
focal plane shutters.
When a lens is stopped down, the eective shutter speed
becomes longer, consequently aecting the set exposure.
At slow shutter speeds the eect is minimal but at faster
speeds, e.g. 1/500s, the eect becomes clearly visible. As
Hasselblad knows exactly how the shutters behave in HC
lenses, automatic compensatory measures in speed setting
adjustments are therefore employed.
As compensation can only be put into eect where speeds
can be adjusted, this prevents the possibility of adjusting
the fastest speed of 1/800s. To counter this, compensatory
adjustments are therefore made to the aperture instead to
retain the set exposure.
However, this compensation is not always required and
when using ash/strobe as the main light source it is actually
undesirable because compensation will result in underex-
posure. Therefore, when using ash/strobe as the main light
source, you should set True Exposure to OFF in Custom
Options #13 on grip.
